FUEL OILS BASED ON MIDDLE DISTILLATES AND COPOLYMERS OF ETHYLENE AND UNSATURATED CARBOXYLIC ESTERS

摘要

The invention relates to fuel oils containing A) a mineral oil having a cloud point of less than -8.degree.C, a boiling range (90-20%) of less than 120.degree.C and a difference between CFPP and PP of less than 10.degree.C and B) one or more copolymers containing bivalent structural units of the formul a B1) -CH2-CH2- (1) and one or more of the bivalent structural units B2) B2) -CH2-CR1R2- (2) in which R1 is hydrogen or methyl and R2 is COOR3, OR3 or OCOR3, R3 being a n alkyl radical having at least 4 and at most 30 carbon atoms, or wherein component B2) is a bivalent structural unit of the formula (2a) (see Formula 2a) derived from maleic acid.
